How to Generate Network Captures for Troubleshooting

When working with Saltmine Support, we may sometimes ask you to collect a network capture, which can be used to record the HTTP data traffic of the affected application. There are different types of network captures available. Some are built into the browser and can debug web-based apps, and some are third-party debuggers that can capture traffic on any platform including web, desktop, and mobile.

Saltmine Support uses this information to isolate any issues or unexpected behavior. For the most part, we may ask you to collect a HAR capture, a Fiddler capture, or a Charles capture.

In general, the process goes:

  1. Start the capture
  2. Reproduce the behavior
  3. End and save the capture
  4. Send the file to Saltmine Support for review

HAR
